SALATU ‘L-KHAUF. صلاة الخوف
The “Prayers of Fear.” Two rak’ahs of prayers recited first by one regiment and then by another in time of war, when the usual prayers cannot be recited for fear of the enemy. These prayers are founded upon an injunction in the Qur’ani, Surah iv. 102: “And when ye go to war in the land, it shall be no sin for you to curtail your prayers, if ye fear that the enemy come upon you?” This was also the Talmudic law (Tr. Beraehoth iv. 4); “He that goeth in a dangerous place may pray a short prayer.”
